Three-dimensional modeling of the plasma arc in arc welding
Journal of Applied Physics, 2008Most previous three-dimensional modeling on gas tungsten arc welding (GTAW) and gas metal arc welding (GMAW) focuses on the weld pool dynamics and assumes the two-dimensional axisymmetric Gaussian distributions for plasma arc pressure and heat flux. In this article, a three-dimensional plasma arc model is developed, and the distributions of velocity ...

Modeling of reactive soluble ARCs and photoresist-ARC interaction
SPIE Proceedings, 2004The stringent requirements facing modern chemically amplified photoresists and antireflective coatings make computer physical simulation methods a valuable tool for photoresist and ARC research and design. Hypothetical microlithographic processes involving toolsets that are unavailable to the experimenter may be evaluated.

Abstract Unipolar arcing occurs when a plasma of sufficiently high electron temperature interacts with a surface. Without any external voltage applied, many electrical micro-arcs burn between the surface and the plasma driven by local variations of the sheath potential with the wall acting as both the cathode and anode. Unipolar arcing represents the

Hydrodynamic Model for Electrical Arc Modeling
IEEE Power Engineering Review, 1996A hydrodynamic model for electrical arc modelling is presented. The model, which takes into account Joule heating, radiation, Laplace forces, arc-wall interactions and real gas effect, has been validated through comparisons with measurements. Industrial applications have already been computed and concern high, medium and low voltage circuit breakers.

The KeyGraph Perspective in ARCS Motivation Model
Sixth IEEE International Conference on Advanced Learning Technologies (ICALT'06), 2006This study examines the learning motivation by means of the traditional ARCS questionnaire and the new technology KeyGraph method. The purposes of the study are to provide pictures of the ARCS model in scenario map format, to supple information in facts and in possible chances, to identify the important elements of each factor in the ARCS model in four

Parameters influence in electric arc modeling
2013 IEEE 8th International Symposium on Applied Computational Intelligence and Informatics (SACI), 2013The aim of this research is to study parameters influence in the electric arc modeling. In order to perform this, a study of the electric arc behavior was made by implementing three models of the electric arc in the Matlab/Simulink environment. Furthermore, graphical user interfaces in Matlab were developed, the purpose being to obtain the dynamic ...

Extending the ARC model with generative coordination
Proceedings of the 2007 ACM symposium on Applied computing, 2007The ARC (Actor, Role, Coordinator) model extends the actor model with roles and coordinators to achieve a behavior-based coordination model that preserves the semantics of the actor model. An ARC role coordinates a dynamic set of actors whose intensional representation and membership criteria are defined by a static description of abstract behavior. An

Modeling of A Resistance Regulated ARC Furnace
IEEE Transactions on Power Apparatus and Systems, 1985An electric arc furnace is a load with a definite impact on the power system. Some of the impacts include harmonics, voltage flicker, and increased power system losses. The objective of this study was to develop a model for analysis of the electrical characteristics and electrical parameters affecting the behavior of an arc furnace load.
